Question

There are n trading posts along a river numbered 1,
2, 3, ..., n. At any of the posts you can rent a canoe
to be returned at any other post downstream. (It is
impossible to paddle against the river, since it is too
fast..) For each possible departure point i and each
possible arrival point j (> i), the cost of a rental from i
to j is known: it is C[i,j] > 0. However, it can happen
that the cost of renting from i to j is higher than the
total costs of a series of shorter rentals from i to j. In
this case you can return the first canoe at some post
k between i and j and continue your journey in a
second (and, maybe, third, fourth ...) canoe. There is
no extra charge for changing canoes in this way.
Give a O(n2) time dynamic programming algorithm
to determine the minimum cost of a trip from
trading post 1 to trading post n.

For tax purposes an item may be depreciated over a period of several years, n.With the straight line method of depreciation, each year the item depreciates by 1/nth of itsoriginal value. With the double declining balance method of depreciation, each year the itemdepreciates by 2/nths of its value at the beginning of that year. (In the final year it is depreciatedby its value at the beginning of the year.)Write a program using **Visual Basic** that performs the following tasks:1.1 Request a depreciation of the item, the year of purchase, the cost of the item, the number ofyears to be depreciated (estimated life), and the method of depreciation. The method ofdepreciation should be chosen by clicking on one of two buttons.1.2 Display a year by year description of the depreciation.

You are given the arrival and departure times of trains reaching to a particular station. You need to find minimum number of platforms required to accommodate the trains at any point of time. Trains arrival [9:00, 9:40, 9:50, 11:00, 15:00, 18:00] Trains departure = [9:10, 12:00, 11:20, 11:30, 19:00, 20:00] The situation can be solved by using few algorithms. However, it will reflect the complexity of the solution. You are required to solve the problem using, (a) Brute Force Algorithm i) Produce the complete algorithm ii) Calculate the minimum number of platforms based on algorithm in (a)(i) and show the process. (b) Greedy Algorithm i) Produce the complete algorithm ii) Calculate the minimum number of platforms based on algorithm in (b)(i) and show the process. Answer part C only (c) Determine the complexity for both Brute Force and Greedy Algorithm for particular problem based on the processes. Justify your answers.

Magnus Carlson has N jars of pickle. They are numbered from 1 to N while it jar contains A; units of pickle. Magnus Carlson believes that ith jar should contain at least Bi units of pickle. Unfortunately, it happens that A; is less than B;. To fix this issue Magnus Carlson adds pickle by doing M operations. Each operation is defined by four numbers 1, r, x and y. It means that Magnus Carlson adds x units of pickle to the Ith, x + y units of pickle to the (1+ 1)th jar, x+ 2y units of pickle to the (1 + 2)h ja., x+ (r - 1)y units of pickle to the r* jar. After it, Magnus Carlson would like to know for each jar i when it starts to contain at least B; units of pickle, i.e., the minimal number of adding operation that ith jar contained less than B; units of pickle before it, but then started to contain at least B; units of pickle after the operation was applied. Develop a code strictly using only cstdio and algorithm library in C which output the answer for each jar separated by space. If…
7. For n 2 1, in how many out of the n! permutations T = (T(1), 7(2),..., 7 (n)) of the numbers {1, 2, ..., n} the value of 7(i) is either i – 1, or i, or i +1 for all 1 < i < n? Example: The permutation (21354) follows the rules while the permutation (21534) does not because 7(3) = 5. Hint: Find the answer for small n by checking all the permutations and then find the recursive formula depending on the possible values for 1(n).

This assignment uses several heuristic search techniques to find possibly optimal truth assignments for variables in the given Boolean formulas (see the bottom of the assignment). The formulas are in conjunctive normal form (ANDs of ORs). The fitness of an assignment is the number of clauses (ORs) that the assignment satisfies. If there are c clauses, then the highest fitness is bounded by c. However, if the formula is not satisfiable, then you cannot simultaneously make all c clauses true. You will use three of the following seven techniques: DPLL Resolution Genetic algorithms Local search Simulated annealing GSAT WalkSAT You must choose at least one complete algorithm to implement - DPLL or Resolution.
The public utilities commission has decided that the electric company overcharged its customers for two months last year. To make up the difference to the customers, the commission orders the company to decrease each of the next month’s bills by 10%. The city also levies a 3%utility tax, which is to be applied to the bill before it is discounted. Also, the10% discount does not apply to the utility tax. Assume electricity costs $0.16per kilowatt-hour. Write a program to compute the next month’s electricity bill given the number of kilowatt-hours consumed as input
